The compressors herein are driven either electrically or by a belt pulley.
Apart from the electric motor for driving the particular compressor mechanism, an electrically driven compressor comprises an inverter for driving the electric motor. The inverter serves for converting the direct current of a motor vehicle battery into alternating current which is supplied to the electric motor across electric lines.
Conventional electric motors of the electrically driven compressors are implemented with an annular stator core with coils disposed thereon and a rotor, wherein the rotor is disposed within the stator core. Rotor and stator are oriented on a common axis of symmetry or rotational axis of the rotor.
The inverter comprises plug connections for the electric connection with connections of the electric motor, which, in turn, are electrically connected with the coils of the stator. The connections of the electric motor are developed in a connector housing disposed on an end side of the stator oriented in an axial direction of the stator.
In prior art electric motors of electrically driven compressors a connector housing is secured by pressing it onto the stator insulation. The connector housing is fixed in position during the assembly. During operation of the compressor, and thus of the electric motor, the press fit generated during the assembly between the connector housing and the stator insulation can become detached so that the connector housing moves and oscillates relative to the surrounding, in particular relative to the stator insulation which causes material abrasion on the faces that are disposed in contact on one another. The connector housing is connected with the stator insulation with the aid of latching mechanisms, in particular across snap-in hooks.
OBJECTS OF THE INVENTION
The invention addresses the problem of providing a device for driving an electrically driven compressor of a gaseous fluid, in particular of an electric motor, which can be assembled simply and therewith time-savingly.

FIG. 2: the carrier element with a resilient pressure element in a perspective view,

 DETAILED DESCRIPTION
In FIG. 1 is shown in a perspective view a stator 1 of an electric motor as a device for driving a compressor of a gaseous fluid, especially for a motor vehicle climate control system, for the conveyance of refrigerant through a refrigerant circuit. The stator 1 is developed with a stator core 2, coils 3, and insulation element 4 as well as with a carrier element 6.
The electric motor, for example a 3-phase alternating current motor, comprises a rotor, not shown, and the stator core 2 disposed in the radial direction on an outer side of the rotor and therewith disposed about the rotor. Both, the stator core 2, preferably developed as a laminated sheet package, and the insulation element 4, developed of an electrically insulating material, extend along a longitudinal axis 5, that also corresponds to the longitudinal axis of stator 1 and the rotational axis of the rotor, from a first end side to a second end side of stator 1. The insulation element 4 is advantageously developed as an extrusion coating of the stator core 2 and thus forms an integral component.
The coils 3 are developed of a wire wound about a region of the stator core 2 that extends inwardly in the radial direction. The regions, extending inwardly in the radial direction, of stator core 2 have the form of a web and are positioned with uniform distribution over the circumference of an outer wall of stator core 2. Between the wires of coils 3 and the particular regions of stator core 2 the insulation element 4 is disposed which insulates the stator core 2 and the wires of coils 3 with respect to one another. The insulation element 4 is developed at the ends, oriented inwardly and in the axial direction, of the webs so as to be expanded in the axial direction. The end segments projecting thusly of the insulation element 4 serve for fixing the wires, wound about the webs of stator core 2, of coils 3. The stator core 2, the insulation element 4 and the coils 3 form the stator unit of the electric motor.
The insulation element 4 projects at the end sides of stator 1 beyond the stator core 2. At the first end side of stator 1 a carrier element 6 is disposed with a receiving element 7 with connection passages 7 a for a connector housing 7 b with connector ports. The connector ports of the connector housing 7 b serve as a component of an electrical connection between coils 3 of the electric motor and the inverter, for example with the aid of electrically conducting, pin-form connection elements which, passed through the connection passages 7 a of the receiving element 7 of carrier element 6, are plugged into the connector ports of the connector housing 7 b.
In the mounted state of stator 1, the carrier element 6 is in contact in the axial direction, on the one hand, on stator 1, in particular on stator core 2. The outer diameter of the carrier element 6 is herein less than the outer diameter of the stator core 2.
The carrier element 6, moreover, comprises, on the other hand, a resilient pressure element 8 that extends substantially in the axial direction. The pressure element 8 is consequently disposed on the side, facing away from the stator core 2, of the carrier element 6.
FIG. 2 shows in perspective view the carrier element 6 with the resilient pressure element 8 and the receiving element 7 with the connection passages 7 a for the connector housing 7 b with the connector ports. The pressure element 8 and the receiving element 7 are disposed on a common side oriented in the axial direction.
The carrier element 6 comprises a radially oriented circular ring-shaped annular surface 6 a, in particular a sector of a circular ring-shaped annular surface as well as an axially oriented cylindrical annular surface 6 b, which adjoin one another at outer side edges and are disposed in connection with one another. The receiving element 7 for the connector housing 7 b is developed as a subregion of the radially oriented annular surface 6 a.
The cylindrical wall of the axially oriented annular surface 6 b of carrier element 6 is implemented with an outer diameter that is smaller than the outer diameter of the outer wall of stator core 2.
The resilient pressure element 8 is disposed in a region, in particular of an inner side edge, of the radially oriented circular ring-shaped annular surface 6 a, and preferably has the form of an arc or a spring. The pressure element 8, as well as the receiving element 7 for the connector housing 7 b, is developed as a constituent part of the carrier element 6. The carrier element 6 with the radial annular surface 6 a, the axial annular surface 6 b, the receiving element 7 with the connection passages 7 a for the connector housing 7 b with the connector ports and the pressure element 8 is implemented in particular as an integral injection molded element. The integral formation is realized within a molding process.
The pressure element 8 comprises a web 8 a, oriented substantially in the axial direction, and a contact region 8 b, oriented substantially in the radial direction. The pressure element 8 Is connected across a front edge of the web 8 a with the radial annular surface 6 a. At an end, developed distally to the front edge of the web 8 a, the pressure element 8 comprises the contact region 8 b which is advantageously developed as a contact area. In the mounted state of the electric motor the pressure element 8 is in contact with its contact region 8 b on a housing, not shown, of the electric motor. When mounting the stator 1 with the carrier element 6 within the motor housing, which means specifically during the installation or the shrinking or pressing-in of the stator 1 into the motor housing and the pressure of the motor housing applied in the process onto the pressure element 8, in particular the web 8 a of pressure element 8, is resiliently deformed.
FIG. 3 shows in lateral view the stator 1 of FIG. 1 in the mounted state installed within the motor housing of the electric motor. The resiliently deformed pressure element 8 extends with an extent h in the axial direction and with its contact region 8 b is in contact on a mating surface 9, in particular on the motor housing of the electric motor. The pressure element 8 is deformed by a difference h0−h1, where h0 describes the extension of the pressure element 8 in the starting state, or in the non-mounted state of stator 1, and h1 the extension of the pressure element 8 in the mounted state of stator 1 in the motor housing. Therewith applies h0>h1.
As a component of carrier element 6, the pressure element 8 has a rigidity defined and corresponding to the geometry and the mechanical dimensions of the carrier element 6. During the mounting of the stator 1 in the motor housing, between the carrier element 6 and the mating surface 9 as a closed end of the motor housing a force F, in particular a spring force, acting substantially in the axial direction, is built up and in this manner the carrier element 6, due to the resilient properties of the pressure element 8, is pressed in the direction of stator 1, in particular in the direction of the stator core 2. Herein, with the contact of pressure element 8 on the mating surface 9 of the motor housing and the resilient deformation particularly of the web 8 a of pressure element 8, the force F acts onto the carrier element 6. Consequently, after the completion of the mounting of the electric motor, and thus after the completion of the insertion or pressing-in of stator 1 with the carrier element 6 into the motor housing, by means of the deformation of the pressure element 8 a prestress is generated which stays the carrier element 6 and prevents any movement of the carrier element 6 during the operation of the electric motor and therewith of the compressor. The carrier element 6 is herein secured in position specifically in the axial direction.
The pressure element 6 serves herein also for the complete elimination of vibrations of the carrier element 6 during operation of the compressor, independently of the particular operating conditions. The resulting force F is layed out such that all tolerance constellations are covered.
According to a, not shown, alternative implementation, the carrier element is developed with a multiplicity of pressure elements in any distribution over the circumference. By multiplicity is herein to be understood at least two pressure elements. The number and disposition of the pressure elements depends on the geometry of the electric motor, in particular of the carrier element.
